Ever thought of how intermodal containers are secured onto a chassis?

One has to be extra careful when hooking the container to the chassis by ensuring that all the four corners of the container are securely attached to the chassis. How is this achieved? It is achieved by ensuring the integral locking devices on the front and the rear of the chassis are independently well clamped with twist-locks. However, when the integral locking device is defective, chassis are secured by wire-ropes.

If a container is not properly secured well onto the chassis and rests well upon the vehicle, it can cause unintentional damage to the goods in the unfastened container when the vehicle finds a bump while in transit. Integral devices hold the handle in position by the help of gravity.
